77. s SeaLINK can run into problems when the PC s routing table contains more than one default route The two most common situations where this occurs are 1 The PC is multi homed meaning it has more than one network card each of which connects to a different subnet on the LAN 2 The PC has been configured to have redundant default routes with one intended to act as the backup for the other The problem is that SeaLINK needs to determine which gateway address to use for the additional routes see above and with multiple default routes it is forced to guess which gateway is the correct one In lieu of more information SeaLINK will always use the gateway address from the first default route in the routing table In either case listed above this means that SeaLINK may have guessed wrong In the first case the serial server may not in fact be accessible via the network card chosen for the gateway In the second case sometimes the backup gateway address is not online In either situation you will see connection errors occur in the Configuration Wizard even when you have specified a correct IP address There are two solutions to this problem 1 Avoid using default routes when at all possible Unless your LAN can also route to the Internet using a default route to route to other subnets is somewhat misleading If the routing table is adjusted to specify the other subnets directly rather than using a default route then the problem goes
